Title: Circular Knitting Machine for the Manufacture of Ladder-Proof Stockings.
IPC: D04B15/02
Filed: 1967-07-25
Abstract: 1,156,751. Knitting. TEXPATENT G.m.b.H. 25 July, 1967 [26 August 1966], No. 34174/67. Headings D1C and D1K. A loop transfer device in a circular knitting machine comprises transfer elements mounted in a bed revolving at a peripheral speed slightly different to that of the needle cylinder so that loops are transfered by relative movement between the beds. The -axis of the transfer bed is displaced from the cylinder axis towards the transfer zone and may be either inside or outside the needle circle. The path of the end of the elements overlies the needle circle in the transfer zone. In the embodiment shown transfer elements 68 are mounted in a bed 66 overlying and inside the needle circle. Rotation of the bed 66, with the assistance of cam 74 in the embodiment shown, carries the elements towards the needles. Needle loops M of one 'course are engaged by the ends of the elements and carried so as to overlie a closely adjacent needle 3''a. The loop is thereby transferred to a following course. The needles are then raised to engage the transferred loop and the elements withdrawn. The direction of the loop transfer depends on whether the bed speed is faster or slower than the cylinder speed. In a modification (Fig. 10, not shown) the elements are mounted in a conical bed so that longitudinal movement of the elements moves them both radially and axially of the cylinder. The sinkers are provided with a lower throat so that a turned welt may be knitted. In the embodiment of Fig. 8 (not shown) a welt dial is provided, and a cylindrical transfer bed (48) is rotatable on a bearing member (47) fixed to the dial cover. The sinkers are recessed in front of the throat free passage of the lowered elements, in a further machine having a welt dial, the elements are carried in a rotatable bed (81 Fig. 14, not shown) mounted outside the needle circle. The elements (80) are arranged generally radially of the bed and have bent-down ends (90) which overlie the needles in the transfer zone. Radial and axial movement of the elements are controlled by cams (92, 94 respectively).

Abstract: 195,041. Leedy Manufacturing Co., (Assignees of Strupe, C. H.). March 16, 1922, [Convention date]. Drums.-In a kettle-drum the head is initially tensioned by spaced tuning-units which are displaced away from their abutments by preferably pedal-controlled means to vary the initial tension, their connection to the tuning-members being such that the drums may be dismounted without disturbing the initial tension. The leverage produced by the pedal may increase with the resistance due to the increased tension of the head. The head 12 is initially tensioned by the finger-nuts 17 bearing on eyes 15 attached to the pressure-ring 14 which depresses the flesh-ring 13. The nuts 17 screw on the tuning-pins 18 which have heads abutting upwardly within inverted cups 20 attached to the kettle 10. These beads are connected by links 22, pivoted plates 23 and pull-rods 25, to a main pull-rod 28. The kettle 10 rests in an inverted open-sided cone 35 detachably attached to a fitting 38 by screws engaging key-hole slots, the fitting 38 being pivotally mounted on a bolt 45 on the pedestal head 43. The drum can be held in any angular position on the bolt 45 by a screw 46 and nut 49, the screw passing through blocks 48 pivoted on the fitting 38 and head 43. The screwed end of the main pull-rod 28 can be readily attached to and detached from a block 30 by means of a finger-collar 37. The block 30 is connected by links 74 to a pedal 50 pivoted on the bolt 45, and by other links 72 to a fixed ratchet segment 52. The pedal 50 carries a plurality of graded pawls 53, permitting of fine tuning, which may be raised out of engagement with the segment 52 by depressing a foot-piece 63, that, by means of a rod 59, brings a spring-retracted pivoted plate 56 against the heels of the pawls. Pressure on the pedal 50 draws down the main pull-rod 28 through the links 74 with increasing leverage, the pull being transmitted by the rods 25 to the tuning pins 18, the heads of which are drawn away from their abutments in the sockets 20. In a modification, the links 72 are omitted and the block 30 is guided in the ratchet-plate.

Title: Current amplifier
IPC: H03F3/345
Filed: 1974-08-06
Abstract: 1465499 Transistor amplifier RCA CORPORATION 6 Aug 1974 34540/74 Heading H3T A current amplifier has two FETs 307, 311 with their sources connected to a common terminal 301, their gates interconnected and the drain of one 311 connected to the source of a third FET 309 whose gate and drain are respectively connected to an input terminal 303 and an output 305. The dram of FET 307 is direct current connected to the interconnected gates. A potential regulating means 308 is connected between the input 303 and the interconnected gates to maintain the potential between input and gates substantially smaller than V GS  of a self-based transistor of the same type as the FETs 307, 309 and 311 but larger than the V DS  sat. The potential regulator may be a string of diodes 308-1, 308-2 poled to conduct the drain current. The input current to the amplifier may be derived from an avalanche diode (523, Fig. 5) not shown via resistance (524) to compensate for the thermal charge in the V DS  of FET 307 thereby maintaining the output current constant. The number of diodes making up the potential regulator can be chosen to temperature compensate the output current. A second potential regulator 313, which can be a plurality of diodes, may be connected between the drain of FET 307 and the first potential regulator 308 and which in conjunction with the first maintains the potential V GS309 + V 308  substantially equal to V GS309  The drain electrode of FET 307 may be direct coupled to the interconnected gates of 307, 311 (Fig. 3, not shown). The circuit can be used as an active load for a bipolar transistor (509, Fig. 5, not shown) which itself can drive complementary FETs (511, 512) forming an output stage. The circuit can also supply the current for a long-tailed pair (501) and it is possible for the first FET and the potential regulators to be used in common with at least two independent series strings of FETs (531 and 532, 533 and 534) for use in an integrated operational amplifier.

Filed: 1958-10-29
Abstract: 866,375. Transistor pulse generating circuits. SNEATH, O. B. Oct. 28, 1959 [Oct. 29, 1958], No. 34571/58. Class 40(6) [Also in Groups VI and XL(b)] Trains of pulses are produced by interrupting, be means of a transistor, longer pulses which are applied to a transformer, the transformer having a step up ratio to a potentiometer for regulating the output voltage. The Figure shows a squegging oscillator of the type described in Specification 864,959 comprising a transistor T1, tuned transformer L1, C3, and a time constant circuit including potentiometer R2 and capacitors Cl, C2, the arrangement being such that variation of the setting of the potentiometer gives a wide range in the repetition frequency of the sawtooth shaped pulses produced by the circuit. These pulses are applied through an emitter follower transistor T2 to a transistor T3 so that each pulse progressively charges capacitor C5. The voltage across this capacitor forms the collector supply source for a blocking oscillator transistor T4 which, when the voltage across the capacitor C5 rises to a sufficiently high value, commences to oscillate producing high voltage output pulses across the output terminals of a potentiometer R7. The pulses increase in amplitude until the termination of the pulse across capacitor C5 when oscillation ceases while the capacitor voltage rises again to a sufficient level to allow oscillation to restart. A switch S2 enables the pulse repetition frequency to be decreased, a switch S1 enables the input to be removed from transistor T2 so that continuous oscillation of transistor T4 takes place, and a switch S3 permits the squegging oscillator circuit to be damped so that continuous oscillation takes place and the operation of the blocking oscillator transistor T4 is interrupted. Terminals MN are provided for an alternative source of supply for the circuit or for recharging the internal source.
